A preloaded ball bearing assembly includes a primary bearing assembly disposed between a rotating component and a static structure. The assembly also includes a preload bearing assembly disposed in contact with the rotating component. The assembly further includes a flexible support disposed between the primary bearing assembly and the preload bearing assembly.

Flexible preloaded ball bearing assembly

An inner ring of an under race lubricated bearing assembly that includes an outer surface, an inner surface, and an inner race formed on the outer surface of the inner ring. A plurality of circumferentially spaced axial slots is formed on the inner surface of the inner ring, and a first set of circumferentially spaced partial circumferential slots is formed on the inner surface of the inner ring adjacent a first end of the inner ring. Each partial circumferential slot intersects at least one of the axial slots. The inner ring also includes a first set of radial holes, where each radial hole extends from the outer surface of the inner ring to one of the partial circumferential slots.
